Abstract

In this paper, we propose an adaptive M-ary Quadrature Amplitude Modulation (M-QAM) transmission scheme that jointly uses selection combining and power loading over multiple independent and identically-distributed (i.i.d) Raylcigh fading channels in multi-channel systems. We derive exact closed-form expressions of the performance of the proposed scheme in terms of the spectral efficiency, the average BER and the outage probability. Numerical results show that our proposed hybrid scheme offers higher spectral efficiency and lower outage probability than the conventional scheme and other hybrid schemes presented in the literature, is more reliable in low SNR region as well.
